•This drive contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing, or servicing this assembly. Component damage may result if ESD control procedures are not followed.

•An incorrectly applied or installed drive can result in component damage or a reduction in product life. Wiring or application errors, such as incorrect or inadequate AC supply or excessive ambient temperatures, may result in malfunction of the system.

•This drive contains power storage devices that retain their charge for a time after the removal of main power. Extreme caution should be used when working in and around the drive. It is recommended that main disconnect power to the drive remain off for three minutes prior to approaching connections.

Warnings specific to a particular subject will appear in the manual with the discussion of that subject.

CAUTION

Only personnel familiar with the drive and associated machinery should plan or implement the installation, start-up,and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage.

Upon delivery, verify the item’s nameplate catalog number against the purchase order.

Before the installation and start-upof the drive, a general inspection of the mechanical integrity (i.e., loose parts, wires, connections, etc.) should be made.

General Information

Storage

The drive should remain in its shipping container prior to installation. If the equipment is not to be used for a period of time, it must be stored according to the following instructions in order to maintain warranty coverage:

•Store in a clean, dry location.

•Store within an ambient temperature range of -40to 70 degrees C.

•Store within a relative humidity range of 0 to 95 percent.

•Do not store equipment where it could be exposed to a corrosive atmosphere.

An incorrectly installed system can result in component damage or reduction in product life. The most common causes are:

1.Wiring AC line to drive output or control terminals.

2.EXTERNAL voltage application to control terminals.

3.Incorrect or inadequate AC supply.

Contact factory for assistance with application or wiring.

Input Power Conditioning

The drive is suitable for direct connection to input power within the rated voltage of the drive. Listed in

Table 1 are certain input power conditions which may cause component damage or reduction in product life. If any of the conditions exist, as described inTable 1, install one of the devices listed under the headingCorrective Action on the line side of the drive.

IMPORTANT: Only one device per branch circuit is required. It should be mounted closest to the branch and sized to handle the total current of the branch circuit.

Install Line Reactor

(1) For drives applied on an open delta with a middle phase grounded neutral system, the phase opposite the phase that is tapped in the middle to the neutral or earth is referred to as the “stinger leg,” “high leg,” “red leg,” etc. This leg should be identified throughout the system with red or orange tape on the wire at each connection point. The stinger leg should be connected to the center Phase B on the reactor.

Careful attention must be given to the arrangement of power and ground connections to the drive to avoid interference with nearby sensitive equipment. Be sure to replace all ground connections to their appropriate locations.

RFI

Drives can be installed with an RFI filter, which controls high-frequencyconducted emissions into the main supply lines.

Where it is essential that very low emission levels must be achieved or if conformity with standards is required, the optional RFI filter may be present. Figure 5 displays an electrical schematic for various RFI configurations.Table 2 shows associated RFI filter part numbers.

ELECTRIC SHOCK HAZARD! Service and

maintenance to be performed only by an authorized technician. Disconnect power before opening any access panels.
